What is it called when an atom has more electrons than protons?

What is it called when an atom has more electrons than protons?

Any particle, whether an atom, molecule or ion, that contains less electrons than protons is said to be positively charged. Conversely, any particle that contains more electrons than protons is said to be negatively charged.

Which of these has more electrons than protons?

The answer is anion. Anion is the term used to describe a negatively-charged ion where there are more electrons than the number of protons in the…

What is an atom that has more neutrons than protons and electrons?

Atoms with differing number of protons and neutrons are called isotopes. When an atom has more protons than neutrons, they are very unstable and do not stay that way for long except for protium and helium-3. When an atom has more neutrons than protons, most of these isotopes are radioactive.

Do most atoms have more electrons than protons?

All atoms have the same number of electrons as protons, so the positive and negative charges “cancel out”, making atoms electrically neutral. 1: Electrons are much smaller than protons or neutrons. If an electron was the mass of a penny, a proton or a neutron would have the mass of a large bowling ball!

Why do some atoms have more neutrons than protons?

The reason is that protons, being charged particles, repel each other. As you get to heavier elements, with each new proton you add, there is a larger repulsive force. As the nuclei get larger, the neutron well gets deeper as compared to the proton well and you get more neutrons than protons.

Which element has more protons than neutrons?

According to Wikipedia: Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons.

What does it mean if an atom has more electrons?

ion
If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.

Do atoms have more neutrons than protons?

The stable isotopes of the heavier element have a great surplus of neutrons compared to the number of protons. The conventional explanation of the preponderance of neutrons in nuclei is that because protons repel each other through the electrostatic force they must be diluted by neutrons.

Are there usually more neutrons than protons?

The reason is that protons, being charged particles, repel each other. As the nuclei get larger, the neutron well gets deeper as compared to the proton well and you get more neutrons than protons.

Do atoms have more protons than electrons?

An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.

Which has more mass electron or neutron?

Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron).

What do atoms have more electrons than protons?

It depends on which atom and how many electrons. Electrons are negatively charged and protons are positively charged. Atoms with fewer electrons than protons have a positive charge, they atoms are called cations. Atoms with more electrons than protons have a negative charge, they are called anions.

What do you call an atom that has no electric charge?

If the atom has an electric charge (i.e., it has more protons than electrons, or more electrons than protons), it is called an ion.That is called a neutral atom, because it has no electric charge. If the atom has an electric charge (i.e., it has more protons than electrons, or more electrons than protons), it is called an ion.

What makes up the charge of an atom?

An atom is composed of three kinds of subatomic particles, called the electron, proton, and neutron. The charge of an electron is negative while the charge of a proton is positive, the two are equal and opposite to each other. The charge of a neutron is zero.

What do you call an atom that has lost an electron?

A positive atom, one that has lost electrons, is called a Cation. They could also be referred to as valencies, for example Sodium can be a cation, that has lost an electron, and now holds a positive charge. Negative atoms are called Anions and work the same way.
